Patent ES-420414-A1 (ES)
Title: Refrigerating system including flow control valve
IPC: G05D23/12
Filed: 1973-11-09
Abstract: The compressor delivers hot compressed refrigerant to the condenser. Flow from the condenser to the evaporator is regulated by a thermostatic expansion valve having its sensing points (pressure and temperature) located in the compresser suction line downstream of an evaporator outlet control valve which is the new part in this application. This control valve has a piston type valve which is operated by a pilot valve actuated by the bellows in the suction line. The bellows is part of a charged system incorporating the capillary tube and the feeler bulb positioned in the evaporator fins. The charging fluid is selected to have a different thermal coefficient of expansion than the bulb so that the pilot valve will close at a selected temperature indicative of incipient icing conditions in the evaporator as may be found in air conditioning systems in which the compressor capacity can exceed the evaporator capacity (typical in automotive air conditioning). When the pilot valve closes pressure on the piston valve balances and the spring closes, the piston valve leaving a bleed port open to insure proper lubrication and cooling of the compressor.

Title: Automatic domestic cooking vessel with self-closing valve - is actuated when internal temp. indicates that air has been expelled by steam
IPC: A47J27/08
Filed: 1978-12-01
Abstract: The automatic domestic cooking vessel (1) has an air-valce which closes upon the attainment of a specific internal temp. The specific temp. may be between 5 and 2 deg.C below the boiling point of water, and corresponds to that temp. which prevails when residual air in the vessel has been forced out by generated steam. The temp. is detected by a thermo-sensor which effects the closure of the valve. An electric heating element under the control of a regulator may maintain a temp. superior to boiling point during a controlled cooking period. The period may be controlled by an adjustable timing mechanism which makes allowance for the time elapsing before specific temp. prevails. The timer effects release of the steam at the end of the cooking period.
Patent ES-478297-A1 (ES)
Title: Improvements in or relating to bonding plastics materials to steel
IPC: B05D7/14
Filed: 1979-03-05
Abstract: The present invention relates to bonding a coating of polyarylene sulphide, for example polyphenylene sulphide, to a steel backing by the use of a ceramic or other non-metallic inter-layer or bonding layer.

Patent ES-479374-A1 (ES)
Title: Circuits and methods for multiple control in data processing systems
IPC: G06F13/12
Filed: 1979-04-06
Abstract: In a data processing system in which two or more asynchronous processors operating as masters interchange requests and responses with a control unit that in turn controls a number of peripheral devices and operates as a slave to the processors, repetitive requests from a high speed processor can give rise to an impasse condition in which the control unit is blocked from completing the previously initiated sequence between a peripheral device and another processor. In accordance with the invention, the interface between the processors and the peripheral devices incorporates means which detect an uninterrupted sequence, of predetermined length, of busy responses from the control unit. If such responses are not interrupted by other actions, the system temporarily exercises independent control, returning a busy signal to the processors while enabling the control unit to ascertain whether reconnection to a specific processor is needed as the next step in a previously initiated processor program. If so, the control unit is enabled within the predetermined interval to effect the reconnection, either within the allotted time or on a succeeding repetition of the cycle. The exercise of a limited initiative for a predetermined time interval does not alter the basic master-slave relationship or unduly delay data transfer operations.

Abstract: A semi-automated warehousing system for unitized loads, such as load carrying pallets, which are retained in storage racks arranged in a multiple lane, multiple tier array is provided. The system employs a man operated stacker crane that travels upon a fixed rail and serves as a host vehicle for a ratio controlled transfer vehicle which is powered by a rechargeable battery. An elevator, which forms part of the crane is mounted between masts of the crane and a man carrying cab is secured to the elevator. The transfer vehicle can move laterally away from the crane, in either direction, in response to radio command signals controlled by the operator in the cab. The transfer vehicle rides on support rails in the storage racks and, upon command, deposits or picks up a pallet. The battery which powers the transfer vehicle is recharged each time the vehicle returns to the elevator portion of the crane.
